74AHC574BQ: 八频D型触发器;正边沿触发器;三态

74AHC574;74AHCT574是高速硅栅CMOS器件并且与低功耗肖特基TTL(LSTTL)引脚兼容。它们符合JEDEC标准No. 7A。

74AHC574;74AHCT574是八路D类触发器,具有用于每个触发器的独立D类输入以及用于总线应用的三态输出。时钟(CP)和输出使能(OE)输入常用于所有触发器。

八个触发器会存储它们各自的D输入状态,满足CP从低到高转换的建立和保持时间要求。

OE为低电平时,八个触发器的内容在输出处可用。OE为高电平时,输出会进入高阻抗关断状态。OE输入的操作不会影响触发器的状态。

74AHC574;74AHCT574在功能上等同于74AHC564;74AHCT564具有非反相输出。74AHC574;74AHCT574在功能上等同于74AHC374;74AHCT374具有不同的引脚排列。
